A vacuum head is a device used in swimming pools to clean debris from the water's surface and floor. It typically connects to a pool vacuum hose and is powered by a pool pump, creating suction that pulls dirt, leaves, and other particles into a filtration system. Vacuum heads come in various shapes and sizes, designed for different types of pools, including in-ground and above-ground models. These cleaning tools can be manual or automatic. Manual vacuum heads require the user to guide them around the pool, while automatic models move independently, using programmed paths to ensure thorough cleaning. Both types help maintain the cleanliness and hygiene of pools, contributing to a better swimming experience.
